13 Claims.

is to provide mechanism for automatically vcutting pintles of suitable lengthfrom an intermittently fed wire. Another object of the invention is to provide automatic mechanism for applying the cut pintle to an emblem to pivotally secure a clasp pin thereto.

A further object of the invention resides in mechanism for riveting the ends of the pintle in such fashion that the pivotal joint will be va .desirably stiff and durable one in orderzto facilitate attachment of the emblem to a garment.

Other objects and advantageous features of the invention will .become apparent in the following description.

The invention consists generally of mechanism for intermittently feeding the wire .into a combined cutter and carrier which operates to first cutoff a pintle of a predetermined lengthyand then to carry the cut increment into'registration with a retractable work-positioning pin mounted on an anvil, and which pin is in alignment with the terminal pin of a plunger reciprocably mounted for pushing the pintle through the carrier and into the holes in the jaws of a clevis ordinarily attached to an emblem such as the lieutenant bar shown in the drawings, and while the pierced head of a clasp pin is positioned within the clevis, such parts beingrmanually held in alignment on the pin of the anvil.

As the descending plunger pin pushes the pintle into position the latter displaces the anvil pin against the urge of a spring beneath it, until it reaches a fixed position in which it is solidly supported on a contacting surface of the anvil structure. A further slight downward movement of the plunger now causes the carrier to close the jaws of the clevis against the contiguoussurfaces of the head of the clasp pin, and simultaneously pressure is applied to the opposite ends of the pintle by reason of the engagement of such ends respectively with the depressed anvil pin and the plunger pin, resulting in an upsetting or riveting of the ends of the pintle to hold the jaws in such closed position.

The invention will be more fully set forth in the following detail description, reference being had to the accompanying drawings forming a part of this specification in which- Fig. 1 is a side elevation of a pintle applying machine embodying the invention, and in which the parts are shown by broken lines in an alternate position.

Referring now in detail to the drawings, the frame I ll of the machine consists of a plate I l with a base l2 secured thereto for suitable attachment to a bench. g

A plunger 13 i slidably mounted in a bracket l9 secured to the plate II and is in vertical alignment with an anvil 20 adjustably secured to the base lz by bolts 2| which pass through slots' 22 in a base plate 23 forming a partof the anvil structure. The plunger [3 is pivoted at M to one end of a lever it through a'slot I5in'th' 'lever. Lever l6 ispivoted'at I1 to an arm 13' secured to theplate l I. y j

A camlever-ZA is aoljustalolypivoted totl'iplate -l l by means of a bushinglli (Fig...3B )"l'ia ving a cylindricaljbarrel 26 extending through'a' corresponding holein the arm 24,. and an enlarged knurled head 21'; Bushing 251s bored eccentrically to receive a boltZSthraded in theplatel I. By loosening the bolt. the bushingj2'5'rnayfbe rotated to changefthel pi'votal pdintf of thelever,

24 on the plate I for a purpose which will presently be apparent. Lever 24 is Provided with a cam surface 29, and a dwell 36 concentric to the barrel 26 of bushing 25.

Lever 24 is oscillated about the barrel 26 by means of a link 3| pivoted thereto at 32. The other end of link 3| is pivoted to a crank arm 33 secured to a drive shaft 34 suitably mounted transversely above the machine and adapted to be periodically driven by well known single cycle trip clutch mechanism not shown.

Another link 35 is pivoted at its lower end to the lever 24 adjacent the pivotal point of the. latter. The other end of link 35 is adjustably pivoted to lever l6 adjacent pivot point M, by means of a bolt 36 having a cylindrical barrel portion 31 (Fig. 3A) extending through a corresponding hole in link 35, and athreaded shank- Bolt 36 is portion 37' eccentric to barrel 31. secured to lever I6 by a nut 38.

Upon loosening nut 38 bolt 36 may then be rotated, and because of the eccentricity of portion 31 the effective length of link 36 may thus be changed to slightly raise or lower the plunger l3 and correspondingly change its operative relationship to the anvil 28 respecting the riveting operation of the machine.

The wire 39 to be out for the purpose set forth is threaded through a friction detent 40 consisting of a block 4| having an overhanging top plate 42 which is apertured to receive the wire. The face of the block 4| is grooved and a flat spring 43 secured to block 4| is adapted to urge the wire 39 against the groove.

The mechanism for feeding the wire-consists of a one way clutch element 45 (Figs. 2 and 9) secured in the forward bifurcated endof a rock lever 46 which is pivoted to the plate H at 41. The other end of lever 46 is also forked to receive the lower end of an actuating rod 48 pivotally secured at 49 to lever 46. Rod 48 extends upwardly and passes loosely through a block 58 attached to the side of lever -|6, or forming an integral part thereof. Block 56 is provided with an opening therethrough'of sufficient size to freely accommodate rod 48 during the angling of the latter about the pivot 49 while the lever I8 is moving from the position shown in full lines to that indicated in broken lines. Nuts 5| provide an adjustable abutment on rod 48 for engagement by lever" l6 when theblock 50 is approaching the position shown in broken lines, in orderto rock lever 46 and move clutch 45 upwardly along the wire 39, and which is the direction of movement in which the clutch slides idly along the wire 39.

When lever I6 is raised into its full line position the block 50 engages a collar 52 "loose on the rod 48 and which is secured to one end of a coil spring 53 also carried by rod 48. The other end of spring 53 is secured to a boss on a nut 54 threaded on rod 48 and locked thereto by a terminal nut 55. 7

It will now be apparent that the rod 48'will be lifted by the lever l6 acting on the spring 53 which will cause lever 46 to rock into the position shown in full lines and move the clutch 45 to positively move wire 39 downwardly toward a cutter and carrier mechanism 56. During the upward movement of the clutch 45 the wire 39 will be restrained from any participatingmovementby the frictionaldetent 48 through which, however, the wire 39 may be pulled during the positive downward movement of clutch 45. The cutter and carrier mechanism 56 consists a stub shaft 12 which passes through a slot 13 of a guide block 60 secured to the plate I by screws 6|. Guide block 60 is provided with a groove 62 on itsinner face contacting plate II, and has a drilled hole 63 for wire 39 opening into groove 62. Within the groove 82 is mounted a slide 64 having an outwardly extending groove 65 at one end bisecting a hole 64' drilled through the slide. Mounted in groove 65 is an elbow spring 65' formed of bent wire and adapted to engage the cut increment or pintle 6'1 and prevent it from falling away during the movement of slide 64 to the position shown in Fig. 'I. The other end of the slid 64 is provided with a notch 68 adapted to engage a hook 69 on a block-10 slidably mounted in a housing secured to plate Block 1|) has secured thereto in plate II, and carries a roller 14 lying in a plane coinciding with cam lever 24.

An adjustable stop is provided for the block 18 consisting of a bolt 15 threaded in the rear edge of plate II and extending into housing 1|. A look nut 16 serves to secure bolt 15 in a fixed position abuttingblock I8.

Secured to the end of stub shaft 12 which extends slightly beyond roller 14, is a clip 11 to which is fastened one end of a coil spring 18. The other end of spring 18 is secured to a bracket 19 attached to plate Spring 18 urges the block- 16 against the end of bolt 15. By adjusting bolt 15 the position of block 10 may be shifted, and consequently slide 64 will also be shifted to thereby accurately register the drilled hole 63 through the fixed block 60 with the drilled hole 64' through the movable slide 64, so that the wire 39 may be fed into the slide 64 prior to the wire cutting operation, and into engagement with thelower side of groove 62 which limits such feeding movement of the wire.

It will now be understood that each time the wire 39' is fed to the cutter and carrier mechanism 56, the desired pintle length, equal to the depth of the slide 64, will be accurately measured before the cutting takes place. Any excess movement of lever l6 beyond the required stroke will be absorbed by the spring 53.

' 7 Slide 64 is cut away at so that when it is in the position shown in Figure 8 it will be free to rock in guide block 60, notch 68 and hook 69 providing a suitable free connection for such angling of slide 64.

Beneath block 68 and secured to plate. H is a flat spring 8| which extends upwardly around the outer end of block 68 and is provided with a cylindrical end piece 82 adapted, to be engaged by the slide 64 when the latter moves partially out of the block 60. Spring 8| urges the slide 64 against the upper wall of groove 62 at this time in order that it may clear the clevis C of the emblem E.

A terminal pin 83 is adjustably secured to the lower end of the plunger |3 by a set screw 84. Pin 83 is preferably made from piano wire, and can be readily replaced when desired.

Referring to Figure 4, the anvil 20 consists of a cylindrical housing 95 which may be constructed integral with the base plate 23, or separately secured thereto. Housing 85 is bored to receive a plug 86 which is rotatably adjustable, and secured in the housing by a bolt 81 in the desired position. Plug 86 is bored to provide a well for a spring 88 which seats on the bottom wall of the well. Plug 86 is counter bored and tapped for threaded engagement with a spindle 89, and to provide a shoulder 90. Within the spindle is a plunger 9! having a head 92 adapted to contact shoulder 90, and to seat the upper end of spring 88. Above the plunger 9| is a rod 93 which rests on the top of the plunger 9|. Mounted in a drilled hole in rod 93 is a pin 94 also preferably made from piano wire, and which can be readily replaced when worn. Pin 94 projects above the top of the spindle 89 through a hole therein less in diameter than that of rod 93 to provide a shoulder 95 against which rod 93 is urged by spring 89.

When pin 94 is depressed by pin 89 to a point substantially flush with the top of spindle 89, the'head 92 of plunger 9| engages shoulder 99. Pin 94 is then in a solidly backed position on the anvil and free of the yielding support of spring 88.

Spindle 89 is faced off at 96 so that the emblem E can be closely positioned in order that the holes in the clevis C and head of the pin P may be strung on the pin 94 as shown in Figure 10. By loosening bolt 81 the plug 86 and spindle 89 may be turned as a unit in the anvil housing 85 to adjust the position of the faced off surface 96 to suit the convenience of the operator of v the machine.

and relative movements of the parts are such that cam surface 29 will first engage roller 14 and motion will be imparted to block 19 and to the slide 64 toward the right as viewed in Figure 2, and since the wire 39 has been previously fed to the cutter and carrier mechanism 56 at the very end of the previous cycle of the machine, the initial movement of slide 64 will sever the wire, the cut increment constituting the pintle 61 being held in place by the elbow spring 65' while subsequently being carried along in a horizontal plane toward the anvil 29.

When the pintle 61 is brought into alignment with pins 83 and 94 (Fig. '7) slide 64' remains stationary because at this time roller 14 is on the dwell 30 of cam lever 24. Plunger l3 has now brought its pin 93 into a position in which its continued movement, while roller 14 is still on dwell 39, will cause the pintle 61 to be pushed by pin 83 through slide 64 and into the aligned holes of the clevis C. During this operation pin 94 will be depressed and displaced from its former position within the clevis C by the pintle 91, and into a position in which the head 92 of plunger 9| will be in contact with shoulder 99. Hence the pintle will now be applied to the clevis with its opposite ends respectively in contact with pins 83 and 94, and with the shoulder of plunger I3 above pin 83, in contact with the top surface of the slide 64.

The final downward movement of plunger l3 will now rock slide 64 downwardly (Fig. 8), and because its lower surface impinges the clevis supported on the top of spindle 89, the jaws of the clevis will be squeezed firmly together against the head of the pin 0. At the same time pin 83 will press the pintle 97 against pin 94, and the ends of the pintle will be thereby riveted and permanently hold the jaws of the clevis in such closed position to provide a tight pivotal joint for the clasp pin.

During the upward movement of crank arm33 the described parts will be restored to their initial position, spring 18 causing roller 14 to follow the cam surface on cam lever 24 until block 19 is again abutting bolt 15. The operation of the wire feeding mechanism has already been described.

The advantages of the adjustable features of lever 24 and link 35 will now be more fully understood. For example, slide 64 at the end of its forward stroke must carry the pintle into accurate registration with the aligned pins 83 and 94. If it falls short of such registration the cam surface 29 may be advanced by turning bushing 25 counterclockwise as in Figure 1, which shifts cam lever 24 toward the left. Obviously the procedure is reversed if slide 64 moves too far.

Bolt 36 provides a convenient means for finely adjusting the stroke of plunger I3, sometimes necessary because of wear on pins 83 and 94. It will be apparent that cam lever 24 is normally held in a fixed position, and since link 35 is pivotally secured to it, any shifting of bolt 39 will lower or raise lever l6 depending upon the relative position of the eccentric portion 38, and that corresponding movement will be transmitted to plunger l3. Therefore, if the downward stroke of plunger I3 is too short respecting the anvil 20, to perform an effective riveting operation, an adjustment of bolt 39 may be made to secure the desired results.

It is obvious that various modifications may be employed to secure substantially the same results without departing from the spirit of the invention and therefore I do not wish to be understood as limiting myself to the exact form of construction shown, as such modifications will readily suggest themselves to those skilled in the art.
